But if a site needs images or javascript responses from another site, things start to go badly wrong. for example: the bbc uses chartbeat in its pages.

That site doesn't respond to pings. Many use firewalls to block ping. (ICMP ECHO).

the point that i'm saying is that what i'm seeing inital pings to sites being ok but as the bbc and many other sites are multi server, and multi routed (as in therms of gateways to the outside world) that plusnet's problems may well not only be congestion which would latency/speed decreases/other weird things that also there may be dns/routing issues.

All good on Usenet full 20 meg download

Wouldn't a routing issue affect pings though?

You're describing congestion in some transit links and no others. That would show up in pings and in traceroutes and other diagnostics.

I'm wondering if there is some BTwholesale core network congestion. We can't see this as all our traffic is in a PPPoE tunnel across the BTwholesale network.

Not seen that on my connection but I was in late tonight

was run at 2253 so maybe past the main congestion time will try to do one about 2100 tomorrow and see if its worse, 40 meg capped service

I loaded this page:

item request times ! I've seen slower website loading and or times outs effectively

Yep but also could be compounded by routing (not saying it is) because congestion itself can show the same symptoms.

if its inside the BTw Core network then every isp would suffer.

For it to be a issue with BTW then it would also be affecting customers with every isp that uses BT WBMC shared for Backhaul . and there has been a distinct lack of such reports , The core network from what i have read would be the least unlikely place to see congestion, The place it most probably lies is at the handover points, or is a bottleneck within plusnets network including their DPI kit,

No issue with that webpage and using FF36.04 just now:- http://s13.postimg.org/6poanoipz/Telegraph_J_Clarkso...
